I am seeing exactly the same too. I have been playing all weekend but cannot get past the failing of targets to associate. If i manually associate i can get modules to work.
I have tried various kinds of deauth etc too but just like Denningsrogue i cannot ever get targets to associate with the tetra.
Any help greatly appreciated Seb/Darren, unless Denningsrogue managed to solve the issue?
I am using a 12v 1.5A supply as well as 2*usb3 through the eth0 port.
As a future suggestion, It would be great for the EU customers if you could switch to a power adapter where you can change the input plug type.
